PEARCE, OF INDIANAPOLIS, INDIANA, ASSIGNOR T RAILWAY SERVICE AND SUPPLY CORPORATION, OF INDIANAPOLIS, INDIANA, A CORPORATION OF INDIANA WASTE cnmnna Application filed March 13, 1929. Serial No. 346,707.

This invention relates to apparatus for use in waste reclamation and particularly to a cleaner for cleaning the waste after the dirty oil has been extracted therefrom.

The object of the invention is to subject a batch of oil extracted waste to the action of suitable agitating means of a type capable of loosening up the balls or pieces of waste and thereby improving its condition and removing dirt and foreign matter therefrom. The tumbling is conducted in a current of air in the sense that the air in which the waste is tumbled is either the air within the container moved by the material itself or an induced air draft as by the use of a fan.

Heretofore oil extracted waste has been tumbled in a tumbler type of machine, but the present invention carries this apparatus one step further in that it provides additional means preferably at the center for more thoroughly agitating the waste to more thoroughly clean and condition it.

In the arrangement shown in the draw in gs, the invention is well set forth in the following description, drawings and claims.

In the drawings, Fig. 1 is an end view of the machine; Fig. 2 is a vertical section longitudinally of the machine; and Fig. 3 is a vertical section transversely of the machine.

In the embodiment shown, 1 represents a suitable casing having a rounded top 2 and a casing door 3. The upper part of the casing is adapted to receive a revolving cylinder mechanism to be described and at the lower portion of the casing there is a hopper bottom 4 discharging into a suitable cleanout space 5 below it opening out at the back of the machine where a suitable door 7 is provided.

Rotatably mounted in suitable bearings in the end walls of the casing 1 are the trunnions 8 and 9, which form parts of cylinder heads 10. Extending from one cylinder head to the other is a reticulated cylinder 11 of wire mesh or the like having an opening 12 closed by a cylinder door 13. The inner wall of the cylinder 11 is provided with suitable inwardly projecting imperforate bafiies 14 of substantially full cylinder length, such as are common to this type of machine. Four of these bafiles are shown symmetrically disposed Within the cylinder. The trunnions 8 and 9 are holl0w,'the latter having its opening extending out through the end for the reception of a. heater shaft 15. This shaft extends out beyond the end of the casing and beyond the end of the trunnion 9. Upon this shaft within the cylinder is a pair of diametrically opposed imperforate beater arms 16 of substantially full cylinder length, said arms extending outwardly from the center and are of a width such that there is a space left between them and the inner ends of the baffles 14.

The cylinder is to be driven at a tumbling speed by any suitable mechanism and the beater is to be driven at a higher rate of speed by any suitable mechanism and in the drawings one arrangement is shown and it comprises a motor 17 provided with a pulley 18 drivinga belt 19 engaging a pulley 20 arranged upon the end of a compound gear including a pinion 21 engaging a gear 22 upon the trunnion 9 and another larger gear 23 engaging a pinion 24.- upon the shaft 15. By the arrangement of this drive the cylinder is driven at the proper speed and the agitator is driven at a higher rate of speed.

Secured to the shaft 15 beyond the gears is a pulley 25 driving a belt 26 engaging a pulley 27 mounted upon a fan shaft 28 extending through a fan housing 29 projecting from the back of the machine. Within this housing is a suitable fan 30 which agitates the air within the casing. It may agitate the air that is in the casing alone or it may draw in some air from the outside as through an opening 31.

In use the oil extracted waste is inserted through the outer casing door through the revolving drum. The inner and outer doors are then closed and the machine set in motion. As the cylinder tumbles the waste within it the beater on the inside beats the waste, finds it up and assists in shaking out and removing the undesirable materials which pass 95 through the cylinder and are directed into the chamber 5 from which they may be removed periodically.

Having described my invention, I claim:

1. Apparatus for treating journal box 100 waste from which most of the oil has been removed, comprising a rotatable reticulated waste receiving cylinder having a plurality of inwardly extending baffles of substantially full cylinder length, and rotatable beating means'axially arranged within said 0 linder and having oppositely extending eating arms terminating inwardly or short of the inner ends of said cylinder baflles, said beat- 1ng arms being imperforate and of substantially full cylinder length, whereby air cur-;'

rents within said cylinder are produced by said bafiles and said beating arms upon ro tation of said cylinderand said beating means. v r 2. Waste treating apparatus as set forth in .claiml, characterized in that said cylinder baflles are imperforate. V

3. Waste treating apparatus as set forth in claim 1, characterized in that said cylinder and said beating means are rotated at differing speeds.

4:. Waste. treating apparatus as set forth in claim 1, characterized in that additional means is provided for producing air currents within said cylinder.

5. Waste treating apparatus as set forth in claim 1, characterized in that additional means is provided for producing air currents within said cylinder said additional means being located outside of said cylinder and within an imperforate casing enclosing said casing. I

In testimony whereof I hereby aifix my signature. 7 c
